Rare Giant? Civilian figures 1/72 scale unknown

I have found these soldiers, very much in style with Atlantic cowboys. One of them is a woman with a submachine gun! I remember having this figure in 1/35. Most of them seem modern robbers, thieves, a very interesting subject! among the mix, are some of GIANTs american soldiers, and what I think is a copy of a german officer saluting/waving/ordering, as I have a 1/32 which is identical to him.

Somebody copied somebody, and then recopied and relabelled.

 

Any info about them would be greatly appreciated!
